Title: Material for slide contact
Inventor: SAGAWA TAKAAKI
IPC: H01H1/023
Filed: 1981-12-18
Abstract: PURPOSE:To provide a slide contact material of which mechanical and electrical corrosion during sliding is suppressed and contact resistance is stabilized at a low level when said contact material is used in the contact element provided to the outer of the rectifier of a small motor, constituted by adding one kind or more Pt, Ru, Pd or Au to Ag in a predetermined ratio. CONSTITUTION:This slide contact material is constituted from a material obtained by adding 1-5wt% one kind or more Pt, Ru or Pd and additional 0.01- 0.5wt% Fe group metal to Ag. This slide contact material is different from a  conventional product in such a point that a public nuisance problem is not  generated in manufacturing and using a contact element provided to the outer  periphery of a rectifier because Cd is not contained. In addition, because elements such as Pt, Ru, Pd or Au extremely high in free energy of oxide formation compared to Cd, mechanical and electrical corrosion is suppressed. Therefore, the contact element provided to the outer periphery of the rectifier prepared by using the material is low in contact resistance and irregularity and  made stable.

Title: Game equipment
Inventor: NIIYAMA KICHIHEI
IPC: A63F7/02
Filed: 1994-08-30
Abstract: PURPOSE: To suppress the deterioration of a deposit ball by preventing the unrequired return of the deposit ball, an unrequired return operation and a continuous return operation due to mischief and an unrequired operation for various kinds of equipment from being performed by invalidating the return operation of the deposit ball under a prescribed condition when the return operation of the deposit ball is performed. CONSTITUTION: It is judged whether or not a prescribed number of balls is reservoired in a supply bowl 21. Such judgement is passed by the presence/absence of a ball detection signal from a second ball detection sensor 26 installed on the upstream side of the supply bowl 21. When no detection signal from the second sensor 26 exists, it is judged that reservoir quantity is less than prescribed quantity, and when the detection signal exists, it is judged that the reservoir quantity exceeds the prescribed quantity. When it is judged that the reservoir quantity in the supply bowl 21 exceeds the prescribed quantity, decision to disable return is passed, and after that, a routine is returned to a main routine.  Therefore, no return operation for the deposit ball is performed in status in which the prescribed quantity of balls exists in the supply ball, 21, which suppresses the operation of a ball ejection device 11 and the occurrence of an overflown ball.

Title: Electrophotographic image formating device
Inventor: KOIDE JUN
IPC: G03G15/06
Filed: 1996-08-05
Abstract: PROBLEM TO BE SOLVED: To form a high grade image even in a case of changing light emission quantity by approaching developing bias DC voltage to an electrification voltage in decreasing exposure and changing the development bias DC voltage in increasing exposure. SOLUTION: When exposure is decreased, a developing bias DC component Vdc is changed so as to approach to an electrification potential Vd. The dot diameter after exposure decrease thus approaches to the dot diameter before the exposure decrease (standard exposure). Namely, the developing bias DC component Vdc is so controlled as to approach to the electrification potential Vd, when the exposure is decreased, so that the dot diameter can be returned to the almost same size as that before the exposure decrease and highlight density region (coarsely dotted region) caused by decrease in the exposure can be compensated on the contrary, when the exposure by LED is increased by decrease in the temperature, the developing bias DC component Vdc is changed in such a direction as keeping away from the electrification voltage Vd, while the electrification potential Vd is kept stable.
